I don't have time to surf the Internet but the possibility is gives of communication (mainly through email an LJ, at least for me) and the access to the necessary resources and information is something quite hard to be without, I must confess!
It's like having a car; once we get accostumed to be able to go anywere we want or need, whenever we want it, is also very dificult to do without it!
Well, I have to go out for a while, but latter I'll be here as I work a little more.
